11.4" Hadrosaur Jugal (Cheek) Bone - Montana

 
 
This is an 11.4" long jugal (cheek) bone, also known as zygomatic bone, likely from an Edmontosaurus annectens. Edmontosaurus is a type of Hadrosaur, commonly referred to as a "Duck-billed Dinosaur". It was collected from the Hell Creek Formation in Carter County, Montana. The bone preserved decently, though there are many cracks that have been gap filled/restored in the reassembling process. The process (likely "equivalent" to temporal process) that protrudes from the bone is fully restored. The superior/posterior most edge of this jugal bone is restored as well.

Hadrosaurs are frequently referred to as duck-billed dinosaurs and are members of the ornithischian family Hadrosauridae They were fairly common herbivores which roamed Asia, Europe and North America during the Upper Cretaceous Period. Many species of hardrosaurs had distinct crests on their head, some of which had air filed chambers that may have produced a distinct sound. These crests may have been used for both audio and visual display purposes.
